I am looking for a way to programmatically retrieve a list of domains that I own through Google Domains (domains.google.com). I have found APIs available for Google Cloud Domains and Google Domains RDAP but these do not appear to be hooked into my Google Domains account, as when I make the API calls nothing is returned.
Has anyone found a way to do this? I am specifically going to be using PHP but if someone can just point me to the correct API (and possibly documentation) to use?
I was able to reach Google Domains support regarding if there is an API I can use to export a list of registered domains with our account, and the response was "At the moment, we do not have that feature with Google Domains."
